LEATHER-SCOURING MACHINE.

SPECIFICATION forming part 0f Letters Patent N0. 427,101, dated May 6,1890.

Application tiled June 10, 1889. Serial No. 313,719. (No model.)

To a/ZZ 1071/0710/ t may concern,.-

Beit known that I, FRANK MONK, a citizen of the United States, residingat Cincinnati,in the county of I-Iamilton and State of Ohio, haveinvented anew and useful Improvement in Iieather-Scouring Machines,-ofwhich the following is a specification.

My invention relates to that class ot machines used for scouring hidesin the process of manufacturing leather; and it consists in certainimprovements, hereinafter described and claimed.

In the drawings, Figure l is a cross-section of a scouring-machineembodying my invention. Fig. 2 is a rear' view of the machine, theposition of the operator being considered as the front of the machine.Fig. 3 isa view, partly in section, of a yielding push-rod.

A represents a frame, in Which is mounted a revolving scouring cylinderB, provided with abrading-ledges b, of stone or other suitable material,and brushes b. l

C is a shield or guard for the scouring-cylinder, and D a frame, inWhich is mounted a platform or plate E,preferably curved,which serves tosupport the hide and hold it in con- 'tact with the cylinder during thescouring loperation.

One edge of the pressurefplate E is pivotally attached to the frame, asat c.

Fis a foot-lever fulcrumed at f, and having pivotally attached to itsend one part G of a The other part sectional yielding push-rod.

G of the push-rod is pivotally attached to the pressure-plate at c". Thepart Ghas a sleeve g, int-o which takes a doWel-pin g upon the sectionG. II is a rubber sleeve taking over and extending somewhat above thesleeve g. Both parts of the push-rod are provided with flanges g2.

The operation is as follows: The hide is placed over the pressure-plateand brought into Contact with the brushes and abradingledges on therevolving cylinder by pressing upon the foot-lever, and thereby raisingthe pressure-plate. The yielding push-rod permits the pressure-plate toyield and adjust itself to any irregularities or differences inthickness in the hide which is being treated,.

and prevents injury from a too positive engagement With theabrading-ledges.

It is obvious that a spiral spring may be used in place of the rubbersleeve.

I claim as my invention- The combination, in a leather-scouring machine,of a rotating scouring-cylinder B, a pressure plate or table E,pivotally mounted at one end,a foot-leverF,a yielding push-rod G G',connecting the pressure-plate and the foot-lever, and a spring II,interposed between the foot-lever and the pressure plate or table.

FRANK MONK.
